i inserted the facebook like box into a cmsimplewebsite and it works quite well, but when the content is edited via the backend-login, the whole <div> defining the like box disappears. i tried to enter the lines for the <div> manually in the source code of the cmsimple-editor, but this does not work; the code is simply not saved.
does anyone know why this happens?

@ maxim: thank you. i tried the wrapper. i installed the plugin, copied the code into the content page but i could not make it work.

@ mcb: faceblink seems to only work for likebutton, sharebutton and facebook-link. i don't know how to use it with the facebook like box.

what do i have to add to avoid that tinyMCE deletes my sourcecode for the likebox?

O, that's the wrong file! (the documentation should clarify this). You have to look under plugins/tinymce/inits/. There are several files init_*.js; you have to edit the one you're using (see the plugin back-end of TinyMCE -> Toolbar). There you have to add the following line:

oh, that was crossposting - in the meantime i found the right js-file, as you can see in my (edited) previous post.
thank you for your advice - i think i am slowly getting behind this riddle. i will try out your suggestion.
